To eliminate the need for AC wiring, the 9160 G2 Wireless Gateway is compliant with IEEE
802.3af and can be powered over its Ethernet connection. For detailed information, please
see "Power Over Ethernet Requirements" on page 323.
Warning: To avoid electric shock, the power cord protective grounding conductor must
2.1.4.2 Antennas
The type of antenna required for each installation depends on the coverage requirements and
the frequencies used. A maximum of four antenna elements can be used. These antennas can
be a combination of reverse thread SMA "screw-on" diversity or high-gain WDS antennas.
There are several omnidirectional antennas and special, directional antennas available from
Psion Teklogix. Generally, a site survey determines the appropriate antenna. Consult Psion
Teklogix service personnel for more information.
Warning: Never operate the 9160 G2 without a suitable antenna or a dummy load.
Connection To Outdoor Antenna (Kit P/N 1916641)
The antenna must be installed by a qualified service person and installed according to local
electrical installation codes. The antenna should be located such that it is always at least 15
ft (4.6 m) high and 10 ft (3 m) from the user and other people working in the area.
For a 9160 G2 connecting to an outdoor antenna, all the following notes are applicable:
1. The shield of the outdoor antenna coaxial cable is to be connected to earth (independent
of the 9160 G2) in the building installation, provided the installation is acceptable to the
authorities in the country of usage.
2. A supplementary equipment earthing conductor is to be installed between the 9160
G2 and earth—that is, in addition to the equipment earthing conductor in the power
supply cord.
3. The supplementary equipment earthing conductor may not be smaller in size than
the unearthed branch-circuit supply conductors (min 0.75 sq. mm nominal cross-
sectional area or 18AWG). The supplementary equipment earthing conductor is to
be connected to the 9160 G2 at the terminal provided, and connected to earth in a
manner that will retain the earth connection when the power supply cord is
unplugged. The connection to earth of the supplementary earthing conductor shall
be in compliance with the appropriate rules for terminating bonding jumpers in the
country of usage. Termination of the supplementary equipment earthing conductor
always be connected to ground.
